C# 向WCF REST（json）发布请求-WebException（400）错误请求

我想通过web服务（REST-WCF）上传一个文件到db，但我有WebException（400）错误的请求，我读了很多解决方案，但我的代码仍然不工作

.config

                <endpoint address="mex"
                          contract="IMetadataExchange"
                          binding="mexHttpBinding"/>
            </service>
        </services>
        <behaviors>
            <endpointBehaviors>
                <behavior name="webHttpBehavior">
                    <webHttp/>
                </behavior>
            </endpointBehaviors>
            <serviceBehaviors>
                <behavior >
                     <!--To avoid disclosing metadata information, set the values below to false before deployment--> 
                    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                     <!--To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information--> 
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>

和我的请求代码：

private void btnUpload_Click(object sender, EventArgs e)
{

    OpenFileDialog open = new OpenFileDialog();
    open.Filter = "Wave files (*.*)|*.*";
    if (open.ShowDialog() == DialogResult.OK)
    {
        string WaveLocation = open.FileName;
        txtUpload.Text = WaveLocation;
        byte[] WavebyteArray = File.ReadAllBytes(WaveLocation);

        ///webClient//////////////////////////////////////////////
        WebClient Proxy1 = new WebClient();
        Proxy1.Headers["Content-type"] = "application/json";
        MemoryStream ms = new MemoryStream();
        DataContractJsonSerializer serializerToUplaod = new DataContractJsonSerializer(typeof(byte[]));
        serializerToUplaod.WriteObject(ms, WavebyteArray);
        byte[] data = Proxy1.UploadData("http://localhost:1866/TransferService.svc/UploadFile", "POST", ms.ToArray());
        MemoryStream stream = new MemoryStream(data);
        DataContractJsonSerializer obj = new DataContractJsonSerializer(typeof(byte[]));
        var guID = obj.ReadObject(stream);
        lblUpload.Text = guID.ToString();
        //////////////////////////////////////////////////////////
    }

我认为问题在于您将内容类型设置为application/json。但您正在体内传递一个字节数组。这可能会混淆WCF。尝试使用任何流，而不是将内容类型用作json

如何使用任何流作为内容类型？您应该使用application/octet stream我使用它，但我仍然有相同的例外：（这可能是答案：请参阅

private void btnUpload_Click(object sender, EventArgs e)
{

    OpenFileDialog open = new OpenFileDialog();
    open.Filter = "Wave files (*.*)|*.*";
    if (open.ShowDialog() == DialogResult.OK)
    {
        string WaveLocation = open.FileName;
        txtUpload.Text = WaveLocation;
        byte[] WavebyteArray = File.ReadAllBytes(WaveLocation);

        ///webClient//////////////////////////////////////////////
        WebClient Proxy1 = new WebClient();
        Proxy1.Headers["Content-type"] = "application/json";
        MemoryStream ms = new MemoryStream();
        DataContractJsonSerializer serializerToUplaod = new DataContractJsonSerializer(typeof(byte[]));
        serializerToUplaod.WriteObject(ms, WavebyteArray);
        byte[] data = Proxy1.UploadData("http://localhost:1866/TransferService.svc/UploadFile", "POST", ms.ToArray());
        MemoryStream stream = new MemoryStream(data);
        DataContractJsonSerializer obj = new DataContractJsonSerializer(typeof(byte[]));
        var guID = obj.ReadObject(stream);
        lblUpload.Text = guID.ToString();
        //////////////////////////////////////////////////////////
